The codex functions as an illustrated legal argument and is divided into several thematic sections: •
Geography and History: The manuscript begins with two maps of the Tepetlaoztoc territory and details the genealogy and history of its pre-Hispanic lords. •
Comparison of Tribute: It documents the "reasonable" tributes paid to indigenous rulers before the conquest to contrast them with Spanish demands. •
Catalogue of Exactions: A meticulous record of Spanish demands between 1522 and 1556. This includes gold jewelry, obsidian mirrors, emeralds, livestock, firewood, and the labor of
tamemes (human carriers). •
Documentation of Violence: The manuscript is notable for its graphic depiction of colonial violence. It features "figures of the dead"—shrouded bodies in horizontal positions—marking deaths caused by overwork, physical punishments, and torture. Images show indigenous people being hanged, whipped, or beaten with sticks for failing to meet tribute quotas. == Physical description ==
